I'll second Skandi's comment about straightness. The fabrics all are easier to deal with if straight. Also good for drip irrigation lines.
On the 10M front, I'd be flexible to some 8-9M rows "fitting the plan" since you can just roll up some extra fabric on those rows.
I'm heading towards another point... in your lower left hand block the direction of the rows changes, presumably for a strict adherence to the 10M length.
The change in direction can be frustrating (I know from experience on our farm) both for walking, and even more so for moving carts/wheelbarrows/equipment like a 2wheel tractor.
I also like the filling in with perennial or "spreading" crops in the weird spaces.
